Five Generations of Solar Inverters

What are the different types of solar inverters?

Each type of solar inverter has its unique features and applications, making the choice of inverter a critical decision in the design of a solar energy system. In this guide, we’ll explore the various types of solar inverters, including string inverters, central inverters, microinverters, power optimizers, and hybrid inverters.

What is a solar inverter?

Inverters are a crucial part of any solar power system, responsible for converting the direct current (DC) generated by solar panels into the alternating current (AC) that powers our homes and appliances. Although they often operate quietly in the background, inverters have been central to the evolution of solar energy systems.

How to choose a solar inverter?

Check the rated power of the inverter against the total power of the solar panels installed. In on-grid systems, the inverter is usually sized a little below or close to the power of the modules (for example, a system with 5 kW of boards can use a 5 kW or 4.6 kW inverter, as small losses can occur).

When did inverters become part of solar power?

By the 1920s and 1930s, technology had advanced, and engineers began creating more efficient and compact electronic devices for converting DC to AC, mainly for industries and electric railways. However, it would take decades for inverters to become part of the solar power industry.
